With the Crystal Growing Chemistry Laboratory Kit, introduce the concepts of saturation and crystal structure. Students grow crystals of alum, chrome alum, cupric sulfate, and more, each with its own distinct color and shape.
Diamonds are a girl's best friend! Stimulate student interest by growing 15 multi-colored “jewels” in your laboratory! In this hands-on activity, students will grow crystals of alum, chrome alum, cupric sulfate, nickel sulfate, and sodium chlorate—each with its own distinct color and shape. Each crystal is grown from a single seed crystal in a supersaturated solution. Watch students take ownership of their crystal and nurture it as it grows over a period of several weeks. This activity is a great way to introduce the concepts of saturation, supersaturation, and crystal structure. Includes thread, index cards, instructions, and enough chemical starting material to grow three of each crystal mentioned above, for a total of 15 crystals.
Complete for 30 students working in pairs. Fifteen glass jars are needed for growing crystals and are available separately.
